Veteran musicians Neil Finn and Nick Seymour — two-thirds of Crowded House's founding line-up — will grace the nation's TV screens tonight when they appear as guests on 7.30 with host Leigh Sales as part of the ABC's Ausmusic Month celebrations.

Following in the footsteps of AC/DC's Angus Young and ex-frontman Brian Johnson, who popped up on the program around this time in 2014, Finn and Seymour field a diversity of questions from the ever-insightful and incisive Sales, who digs into the band's three-decade-strong career and back catalogue to traverse highs and lows, personal favourites and other anecdotes from across their wide-ranging adventure together.

Along with coinciding with Ausmusic Month, the interview comes in conjunction with the announcement of the band's induction into the ARIA Hall Of Fame at this week's ARIA Awards ceremony, and will air ahead of the band's eagerly awaited Crowded House Live At Sydney Opera House event going down and screening this Sunday, 27 November.

7.30 airs at its title time on ABC tonight. Crowded House Live At Sydney Opera House will air on Sunday from 7.40pm on ABC and iview, simulcast on Double J and live-streamed on ABC TV's Facebook page.

If you're not Crowded House'd-out after all that, Double J will be running a special episode of The J Files this Thursday, 24 November, exploring the band's massively influential career, so be sure to tune in for that one.

Crowded House will play shows at the Opera House each night this week from Thursday, 24 November.
